Question

pls answer my both questions

Answer 1

Answer:

Step-by-step explanation:

8. Given, QPR is 80 degrees

and PQ=PR

let the other two angles be x,x because it is an isosceles triangle

by triangle sum property

80+x+x=180

2x+80=180

2x=100

x=50

therefore angle R and angle Q are 50 degrees.

9. PM = 4 CM

Step-by-step explanation:

In triangle PLO

5^2 - 3^2 = PL^2

PL^2 = 25 - 16

PL = √ 16

= 4

Triangle PLO and PMO are corresponding by SAS

THE PM= PM

PM = 4 cm
